One of the main challenges posed recently on pellet launcher systems in fusion-oriented plasma physics is the control of the plasma edge region. Strong energy bursts ejected from the plasma due to edge localized modes (ELMs) can form a severe threat for in-vessel components but can be mitigated by sufficiently frequent triggering of the underlying instabilities using hydrogen isotope pellet inj...

IN the literature on owls, there has been much interest in the formation in the upper gastro-intestinal tract of pellets which contain indigestible material and which are subsequently regurgitated. This feature of gastrointestinal function has interested bird physiologists, and analysis of the pellets has been used to monitor feeding habits (Errington et al., 1940). Although pellet formation is...

Crystal growth experiments (micro-pulling down or Czochralski methods, respectively) and DTA/TG measurements with Fe containing olivines (fayalite–forsterite solid solution) and with FeO (wustite) are performed. For both substances the oxygen partial pressure pO2 of the growth atmosphere had to be adjusted within the stability region of Fe 2+ for all temperatures ranging from room temperature t...

In this study, a pellet scale model was developed for trickle bed reactor utilizing CFD techniques. Drag coefficients were calculated numerically at different velocities and bulk porosities in the case of single phase flow through the dry bed. The simulation results were then compared with the prediction of Kozeny-Carman (K-C) equation. The results indicated that drag coefficients calculated fr...

The effect of pellet diameter on the liveweight gain, feed intake and feeding behaviour of young pigs was examined. Two hundred and thirty four pigs were placed on trial at 10 days of age, whilst still suckling their dam. Pigs were weaned at approximately 28 days of age into fully slatted flatdeck accommodation and remained on trial until approximately 56 days of age. Pigs were assigned to one ...

Intravascular migration of bullets and other foreign bodies is a rare but known complication of penetrating trauma. Missile embolization can represent a diagnostic challenge because it may present in various and unexpected ways. We present the case of a 54-year-old female who sustained shotgun pellet emboli to the pulmonary arteries following a left upper extremity gunshot wound and related vas...

The dependencies of energy confinement on the main engineering parameters have been investigated in the Mega Ampere Spherical Tokamak (MAST) in H-mode by expanding operational space towards higher plasma currents (up to 1.2MA) and heating powers (up to 3.5MW). Multivariate fits show that the dependence of energy confinement time on plasma current Ip is weaker than linear while the dependence on...
